VEGETABLE SHREDDER Filed Jan. 23, 1942 I I ,H (inventor Patented Nov. 3, 1942 UNITED STATES PATENT OFFICE VEGETABLE SHREDDER Nick Knuth, Chicago, Application January 23, 1942, Serial No. 427,899

2 Claims.

This invention relates to improvements in vegetable shredders or juicers and more particularly to those of the portable electrically operated type. The shredder is made in different sizes and capacities so that a selection may be made for family use as well as for commercial use in restaurants, hotels, hospitals and the like. One object is to provide a vegetable shredder that is simple in construction, inexpensive to manufacture, durable in use and positive in operation. A further object is to provide a shredder that is preferably made throughout of stainless steel or other acid resisting metal or, as in the small size, that has its surface metalized so that it is self-cleaning and therefore completely sanitary in use.

A still further object is to provide a vegetable shredder constructed to operate at high speed with practically no vibration, that is noiseless, economical in the use of electric current, that is neat and attractive in appearance, and compact in assembly.

With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described, pointed out in the claims and illustrated in the accompanying drawing, in which- Fig. 1 is a view in front elevation of a vegetable shredder constructed according to the present invention.

Fig. 2 is a vertical longitudinal centralsectional view through the machine on the line 2-2 of Fig. 1.

Fig. 3 is an end view of Fig. 4.

Fig. 4 is a view in side elevation of a cutter employed.

Fig. 5 is a face view of one form of cap for the shredder housing.

Fig. 6 is a view of a modified but usually preferred form of shredder in side elevation.

Like reference characters denote corresponding parts throughout.

The vegetable shredder includes a base I adapted to rest upon a table or like support to carry the motor 2 provided with the drive shaft 4. A shredder housing 5 is provided and comprises a tubular body portion or housing having a mouth 6, a slightly larger discharge end 1 and a substantially enlarged central portion 8 having a contracted front 9 substantially hub shaped and hollow to form a seat, the rear ID of said section being open.

Referring now to Figs. 1 to 5 inclusive, a circular cap or closure II for the rear of the housing portion 6 is formed with a reduced portion I2 adapted to fit snugly inside said rear as the cap is applied thereto, said cap being perforated centrally to receive the motor shaft and recessed from its inner face about said perforation to form a seat corresponding to the seat in the front 9.

The cap is formed peripherally with two pairs of spaced ears l3 and I4 directly opposite each other, each pair of ears being perforated to receive a rivet l5 that pivotally carries a threaded link IS, the threaded portion of each link having thereupon a wing nut I'l. Spaced lugs l8 formed upon each sidewf the enlarged portion 8 of the housing 5 are in the path of movement of the links 5 so that when the same are swung laterally toward the housing the threaded portions of said links are received in or between said lugs. By now tightening the wing huts l1 against said lugs the cap II is drawn tight against the open rear end of the housing enlargement 8 to form a vibrationless closure therefor.

A rotary cutter l9 round in cross section is formed peripherally with spirally arranged rows of teeth 20, the spirals working inwardly from each end of the cutter toward the center so that the material being cut or shredded is worked inwardly from the ends toward the center. The cutter is formed with tubular shafts 30 and with a central recess to receive the end of the motor shaft 4 which shaft is there formed with a flat face portion 2! against which the inner end of the headless screw 22 is received, said screw being introduced through a threaded perforation in the cutter to secure that member to the shaft. The housing 5 is so supported that it is clear of the base I.

A link 23 extending obliquely downward from the cap or closure H is received in the open end of the tubular anchor link portion 24 secured by screw or rivet 25 to the base I to anchor the cap against vibration or play that might otherwise be set up by the motor shaft. The vegetables to be out are introduced at the mouth 6 of the housing and engaged by the cutter l9 and ground, the pulp or ground material being discharged through the lower end of the housing into a container from which the material is removed to extract the juice therefrom. The housing 5 is disposed just beyond the edge of the table or support 3 so that a container may be arranged upon a support just beneath the housing discharge end.

Referring now to Fig. 6 a modified but usually preferred structure is shown. The head of the motor 2 is displaced by a special head 3| that is integral with the cap or closure 32 similar in all respects to the separate closure cap II and formed with a corresponding reduced portion 33 adapted for snug fitting engagement with the open end of the enlarged housing portion. The housing 34 is formed without the contracted front end and the rotary cutter 35 is formed Without the tubular ends 30 of the cutter I9. The cutter 35 is mounted directly upon the motor shaft 4a just as the cutter I9 is mounted upon the motor shaft 4 of Fig. 2. This arrangement comprises less parts, infrequent lubrication in operation, is more free from vibration and is relatively inexpensive to manufacture. No anchor link is necessary in the preferred construction.

What is claimed is:

1. In a vegetable shredder, a base, a housing closing the open end of said central housing portion formed with a seat, a cutter formed with shafts at its ends received in said seats, means for actuating said cutter, links carried by said cap for clamping engagement with said housing, and an anchor link connecting said cap and base.

2. In a vegetable shredder, a base, a housing having an enlarged central portion formed with one open end and a seat at its closed end, a cap closing the open end of said central housing portion and formed with a seat, a rotary cutter formed with shafts at its ends received in said seats, means for actuating said cutter through having an enlarged central portion formed with one open end and a seat in its closed end, a cap said cap, pairs of lugs arranged upon said housing, links pivotally carried by said cap, wing nuts upon said links for clamping engagement with said pairs of lugs, and a sectional anchor link connecting said cap and base.
